Anticholinergic burden in fibromyalgia treatment analysis: Guidelines adherence and pharmacological alerts.
Article in Clinics (Sao Paulo, Brazil), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis study examines the challenges related to pharmacological outcomes in Fibromyalgia (FM), a multifaceted syndrome characterized by widespread pain, cognitive impairment, and fatigue. It aims to evaluate medication use patterns, identify potential drug-drug interactions, assess adherence to clinical guidelines, and determine how these pharmacological factors may contribute to symptoms often described as fibro-fog and influence overall health and well-being.
methodsThis cross-sectional study analyzed medication usage and potential drug interactions in women with FM. Tools such as CheckTheMeds® and the CRIDECO Anticholinergic Load Scale were employed to assess the pharmacological appropriateness of treatments in alignment with clinical guidelines and to quantify anticholinergic burden.
resultsA total of 881 medication alerts were reviewed, corresponding to 108 women with FM (mean age: 54.06 ± 8.43). Pain management medications accounted for 72.94% of the total medications prescribed. The analysis revealed a significant anticholinergic burden in 50.93% of the patients.
conclusionsPharmacological reviews are essential in the management of FM, as they enhance treatment safety, minimize risks such as CNS depression and excessive anticholinergic burden. Optimizing medication regimens may indirectly influence symptoms commonly reported in fibromyalgia, including those often referred to as fibro-fog, while supporting safer and more individualized treatment strategies.
